An informative book about the nine choirs of angels. It inspires me to do my own research, and the author provides many references and footnotes to get one started. I would want to look into this more thoroughly before following all of her advice. I found the writing style somewhat hard to get comfortable with, flowery and repetitive. The theology is somewhat vague, perhaps on purpose? She writes from a Catholic Christian perspective, for everyone of good will, so the book isn't intended to be a theological treatise. The book is an alternative to the ubiquitous New Age material available on the subject of angels, and as such is a valuable contribution to the writing on the subject.
